Add Breadcrumb Navigation to Blogger Blog

What is Breadcrumb Navigation? The graphical control element Breadcrumbs or breadcrumb trail is a navigation aid used in user interfaces. It allows users to keep track of their locations within programs or documents. The term comes from the trail of breadcrumbs left by Hansel and Gretel in the popular fairytale. Breadcrumbs typically appear horizontally across the top of a Web page, often below title bars or headers. They provide links back to each previous page the user navigated through to get to the current page or—in hierarchical site structures—the parent pages of the current one. Breadcrumbs provide a trail for the user to follow back to the starting or entry point.

If you’re new to Blogger, it sounds impossible to have a breadcrumb navigation, but it’s really easy to add breadcrumbs to Blogger blog with few edits. Typical breadcrumbs look like this:

Home page > Category > Post

Navigate to your Dashboard > Template > Edit HTML. Search for the following code:

<b:include data='top' name='status-message'/>

If you found the above code two times, then make sure to do the same thing with the second one. Right before the above code, add the following snippet:

<b:include data='posts' name='breadcrumb'/>

Now search for the following code:

<b:includable id='main' var='top'>

And add the following code just above:

<b:includable id='breadcrumb' var='posts'>
<b:if cond='data:blog.homepageUrl == data:blog.url'>
<b:else/>
<b:if cond='data:blog.pageType == "item"'>
<p class='breadcrumb'>
<span class='post-labels'>
<a expr:href='data:blog.homepageUrl' rel='tag'>Home</a>
<b:loop values='data:posts' var='post'>
<b:if cond='data:post.labels'>
<b:loop values='data:post.labels' var='label'>
<b:if cond='data:label.isLast == "true"'> »
<a expr:href='data:label.url' rel='tag'><data:label.name/></a>
</b:if>
</b:loop>
<b:else/>
»Unlabelled
</b:if>
» <span><data:post.title/></span>
</b:loop>
</span>
</p>
<b:else/>
<b:if cond='data:blog.pageType == "archive"'>
<p class='breadcrumb'>
<span class='post-labels'>
<a expr:href='data:blog.homepageUrl'>Home</a> » Archives for <data:blog.pageName/>
</span>
</p>
<b:else/>
<b:if cond='data:blog.pageType == "index"'>
<p class='breadcrumb'>
<span class='post-labels'>
<b:if cond='data:blog.pageName == ""'>
<a expr:href='data:blog.homepageUrl'>Home</a> » All posts
<b:else/>
<a expr:href='data:blog.homepageUrl'>Home</a> » Posts filed under <data:blog.pageName/>
</b:if>
</span>
</p>
</b:if>
</b:if>
</b:if>
</b:if>
</b:includable> 

That’s it! Save the template and visit your blog posts to see the breadcrumb in action. You can also style your breadcrumb by adding following CSS just above ]]>:

.breadcrumb {
padding:5px 5px 5px 0px;
margin: 0px 0px 15px 0px;
font-size:90%;
line-height: 1.4em;
border-bottom:3px double #e6e4e3;
font-weight:bold;
}

Note: If you are using Bootstrap, You don't really need to add that CSS.
